DM70 is fully calibrated and adjusted as shipped from the factory. The typical calibration interval is 1 year. Calibration must always be done when there is reason to believe that the device is not within the accuracy specifications.
The device can be sent to Vaisala for calibration and adjustment.
| If DM70 is producing incorrect measurements, the recommended first step is to carry out a few (2 ... 4) sensor purges (available in the DMP74B/DMP74C probes) to heat and dry the sensor and check if this solves the issue. For instructions on starting a sensor purge manually, see Performing manual sensor purge. If sensor purges fail to correct the issue, move on to calibration and adjustment. |
